UNITED S'IA'IES]r FREDERICK c. MILES, ory sANQFngNcIsco, Camomilla:

To allwhoma'tmay'concemf.

. Beit knownthat I, .FREDERICK C. -MILEs", vla subject of they King ofEngland, and-resident of San Francisco, county of VSan :Francisco, andk:State of California,: have invented anew and useful Auto Attachment, ofwhich the following isa specification. n

The present invention relatesto improvemen-ts inthe Fordy automobile andits object is to provide animproved bearing means for the rear axlehousing of the same. As at present constructed the two ends of the rearaxle housing are substantially supported by the axle, a roller bearingand a roller bearing sleeve being interposed at either end near thewheel between the axle proper and lthe housing so 'that the weight ofthe housing rests on the axle. It is the object of the present inventionto take the weight of the housing from the axle altogether and have itVsupported by the wheel through the medium of the brake drum so that theonly work to be done by the axle is that of rotating the wheel; Since ithappens not infrequently that the rear axlevbreaks Vright near one ofthe wheels due to the weight of the housing and that part of the machinesupported by the housing, there isrno doubt but what an improvement likethe one proposed in this application should add considerably to thedesirability and longevity of the car.

I attain my object by means of the mechanism illustrated in theaccompanylng drawing, which represents a vertical section through therear hub` and that part of the rear axle housing vaffected by myinvention, my special attachment replacing the roller bearing and rollerbearing sleeve found between the axle and its housingin the Ford car asnow constructed.

Referring to the drawing in detail the reader will see that as in thepresent day Ford car the rear axle (1) extends from the differential(notshown in Lthe'drawing) to the hub (2) of the rear wheel (3) and iskeyed to the hub as shown at (4'). Hub and axle are held in placerelative to eachother by the castle nut (6) screwed on a reducedthreaded extension (7) of the axle andbearing against the outside of thehub through the washer (8), a Cotter pin (9) keeping the nut fromworking loose. cap

screwed on a threaded portion (12) of the hub incloses the end of theaxle. The spokes (14) lof the wheel are secured to the hub beyspeilcation of fettes lPatent i means of 5a pluralityof bolts-`-(l8)which -at the'same time securethe brake drum '(19) to the wheel` as inthey present day car. The

`brake members are shown only in av fragy mentary-way,' because'they donot yin any way affect my invention. The brake. band is indicated at(.21) and a lining (22) between the brake :band and thev brake drum.

-The :axle housing, as yfar as' showninthe drawing, comprises twopart-s, one part (23) extending into the brake drum and supporting thebrake shoe, while the other part (24) connects the part (23) with thecentral part of the rear axle housing inclosing the differential. Thetwo parts are riveted together as shown at (26). As atpresent'conmatthew@ hubfiangeg (16) and (177 by structed there are aroller' bearing and a sleeve for the same interposed between the axleand the part (23) of the housing, allowy ing the housing to rest on theaxle and allowing the axle tov rotate within the housing. I

do not use this roller bearing and its sleevel` and they are, therefore,not shown in the drawing. The space occupied by the two is largely takenup by the sleeve (27 which fits tightly 'into the inside of the housingmember (23) but has an inner diameter exceeding that of the axle, sothat when both are arranged co-axially there is considerable clearancebetween the axle and lthe sleeve (27). The sleeve extends from a pointin the immediate proximity of the joint between the parts (23) and (24)of the housing to the inside of the brake drum, just clearing its innersurface. Inside of *the brake drum' it is provided with a collar (28)forming'an integral part ofthe same. This collar bears againsty thehousing as shown at (25)',andforms 4the inner race of a ball bearing(29), the outer race (31) of which vis rigidly secured to Va flangedring'l (32).

Its flange (33) is provided'with a plurality of perforations registeringwith the holes through the brakev drum, the hub fianges and the wheel,so that'the bolts (18) maybe extended through the same and the ring thusmade an integral' part of the'latter members and be firmly supported bythe same.

At the inner end the sleeve (27) is provided with a vgrease Washer (34)which is secured in place by a metal washer (36), a plurality of setscrews (37) extending through said washers into the end of the sleeve.To prevent the washers from working loose I select such as have largeheads,'

so that the heads have to be led down in order to allow the sleeve to goinside the housing,l which effectively locks the set` screws. t

It will thus be seen that with my attachment the whole weight of therear axle housing will be supported by thevball bearing Y (23) of theaxle housing so as to leave suicient room forV the collarl (28) of thesleeve (27) between the axle housing and the brake drum.y l 1 v Theopening .(41) for the ease cup (42) provided onj the l,Ford maclnefshould be t extendedthrough the sleeveas shown at (43) so that thegrease maybe forced between the sleeve and the axle. A

I claim: Y

In means for supportin the rear axle housing ofV a Ford automo iledirectly on the rear wheels, a reinforcing sleeve secured to the insideof the housing sol as to'elear the axle and ytofextend into the brakedrum, a collar on the sleeve within thebrake drum, a flanged ringywithin the brake drumfpo'sitoned co-axially with the*` collar 'having aplurality of' perforations in its jflange adapted to register with boltssecuring the brake drum to the wheel and to be engaged by the bolts,xandan anti-friction bearing having the collar and the ring for inner andouter races respectively` f Y .Y
